The point about the newer Bialettis being cheaper is absolutely true. My mother has an old (>10 years) Moka that feels heavy and sturdy. A couple of years ago, after accidentally leaving it on the stove for too long, the bottom chamber and the filter basket got a permanent burnt coffee taste, and we bought a new one to replace it. That one was lighter and came with a significant thinner filter basket, which I also at…

James Hoffman gives a good history of Bialetti here: https://www.youtube.com/watch?v=upgQsA5kLAk including their sale to Faema and later to a cookware manufacturer, their numerous brushes with bankruptcy, and the stiff competition they've gotten from... even in Italy... pod machines.

What did you expect? They're not exactly innovators, are they?

Does anyone else get 406 Not Acceptable openresty error on this website?

Seems to me that a bunch of websites block IP addresses with tor relays (not exits), and they all send a `x-cluster-name: eu-west-1-prod-hosting-red` header.

Probably one of AvE's best videos. I was just chatting about the peak Silicon Valley insanity that was Juicero yesterday. That thing was built like a Bugatti. And he's like "why not use a roller instead of a press??".

I love AvE and somehow understand exactly what he's saying whilst simultaneously having no idea what he's saying half the time. Does anyone know if this is some regional slang? Or is AvE just very unique in how he speaks?

It is very Canadian and is full to the brim with references to the Red Green Show, including his sign-off telling you to “keep your stick on the ice”.

Europeans (and other countries with ~230V household sockets) would consider this quite poor performance for a kettle. 3000 W kettles are not uncommon here in the UK!

I have this kettle, and its selling points are: temperature control, ergonomics, and the steady, controllable flow rate. Using it is pure joy! It reaches the desired temperature before I'm done preparing everything else (throw the beans in the grinder, pre-heat the V60, etc), so it does not matter that it can't draw 3kW.

I have a great temperature control kettle (Sage Smart Kettle) which is both fast (3kW) and reasonably precise, to within a couple of deg C.

I’ll give the Stagg EKG some credit for looking very cool, however.

I think - I am an electrical engineer working in the offshore industry, so I have only superficial knowledge of shore-based installations - anyway, I seem to recall that the Norwegian electrical code calls for Schuko not being used to carry more than 10A continously, 16A intermittent. However, until relatively recently, the average residential circuit was 10A, though you could get 16A if you asked for it - typically…

In Sweden (Schuko), 1.5 mm² wall installations are rated for up to 13 A now, but used to be 10 A. It's the wires in the walls being the bottleneck, not the connectors. Dunno why they up-rated it. Can't imagine the copper is better now than it used to be.

It is possible that the copper really is better. AFAIK, a lot of wiring that is sold today is made of high grade oxygen free copper, which, thanks to improvement in manufacturing processes, is barely more expensive than the lower grade stuff.

But even more important is the insulation. It has been consistently improved since cloth wires.

Reads like the product of a co-marketing deal:

FWIW, I owned a Fellow, until it failed. Now happily replaced with an OXO kettle: 1500W; much better ergonomics, at least for those with larger hands; fewer steam burns; more readable temperature display.

Interesting images and a very well put together page. But a little off topic, I was struck by this: > With the powerful 1200 W heating element A typical European kettle is at least 1800 W, comfortably less than the power deliverable from a 10 A, 230 V circuit. A typical UK kettle would be more like 3000 W, such as this one (it seems that all the kettles on that website are 3 kW): https://www.argos.co.uk/product/93631…

I'm not sure what the point is you're trying to make? I'm sure you're aware that US sockets are 110-120V. The power required by a European kettle would too often trip someone's circuit breaker in the US, especially if any other equipment were also plugged in (you usually want to stick to max 1500 W on a circuit). Clearly the "powerful 1200 W" is in the context of equipment designed for American residential sockets --…

The point is that 1200 W in the context of many of the people reading this is not a lot.

Okay pretty cool but I have to give my two cents for the text. A patina does not enhance flavour, that's basically rancid left-over coffee.

Also the plunger in the aeropress isn't pushed through and STILL compressed in the picture (as shown here). To push it all the way through the cap has to be loosened.

The scans are fascinating though :D
